  • logic programming — (artificial intelligence, programming, language)   A declarative, relational style of programming based on first-order logic. The original logic programming language was Prolog. The concept is based on Horn clauses. The programmer writes a "database" of "facts", e.g. wet(water). ("water is wet") and "rules", e.g. mortal(X) :- human(X). ("X is mortal is implied by X is human"). Facts and rules are collectively known as "clauses". The user supplies a "goal" which the system attempts to prove using "resolution" or "backward chaining". This involves matching the current goal against each fact or the left hand side of each rule using "unification". If the goal matches a fact, the goal succeeds; if it matches a rule then the process recurses, taking each sub-goal on the right hand side of the rule as the current goal. If all sub-goals succeed then the rule succeeds. Each time a possible clause is chosen, a "choice point" is created on a stack. If subsequent resolution fails then control eventually returns to the choice point and subsequent clauses are tried. This is known as "backtracking". Clauses may contain logic variables which take on any value necessary to make the fact or the left hand side of the rule match a goal. Unification binds these variables to the corresponding subterms of the goal. Such bindings are associated with the choice point at which the clause was chosen and are undone when backtracking reaches that choice point. The user is informed of the success or failure of his first goal and if it succeeds and contains variables he is told what values of those variables caused it to succeed. He can then ask for alternative solutions.

  • magnetic monopole — a hypothetical very heavy particle with an isolated magnetic north pole or magnetic south pole.
  • maintainer script — (Debian)   One of the scripts (preinst, prerm, postinst, postrm) that may be included in a Debian binary package. These scripts may create and/or remove symlinks, files or directories that, for some reason, could not be done directly by dpkg. Maintainer scripts frequently create or update the symlinks in the /etc/rc?.d directories and start, stop, or restart daemons.

MITRE does not stand for MIT Research and Engineering, though it could have.

  • optical astronomy — the branch of observational astronomy using telescopes to observe or photograph celestial objects in visible light.
  • optical computing — (hardware)   (Or "Optical Signal Processing") Operating on data represented using electromagnetic radiation, e.g. visible light, instead of the electrical signals used in a conventional electronic digital computer. Electronic digital computers are built from transistors. These form components that store data and logic gates that perform the low-level Boolean operations such as AND, OR and NOT that are the basis of all digital computation. The optical equivalent requires material with a non-linear refractive index such that light beams can interact with each other to perform the same Boolean operations. Though the photons that carry optical signals offer some theoretical advantages over the electrons that carry electronic signals, there are many practical problems that would have to be overcome before optical computing could compete in terms of cost, power and speed.
  • over-compensation — a pronounced striving to neutralize and conceal a strong but unacceptable character trait by substituting for it an opposite trait.
  • packaging company — a company that packages goods on behalf of the producer
